Assessing the impact of obturation techniques, kinematics and irrigation protocols on apical debris extrusion and time required in endodontic retreatment.

The aim of the study was to evaluate the impact of kinematics and irrigation protocols on the extrusion of apical debris during removal of different obturation techniques. A total of 144 single-rooted teeth were instrumented and obturated with Thermafil+AH Plus, Thermafil+AH Plus Bioceramic and single gutta-percha cone+AH Plus Bioceramic. Samples were divided according to the retreatment kinematics: continuous rotation or Jeni motion.

Microbiome differences in periodontal, peri-implant, and healthy sites: a cross-sectional pilot study.

Objectives: To explore microbial communities associated with health and disease status around teeth and dental implants.

Materials And Methods: A total of 10 healthy, 24 periodontitis, and 24 peri-implant sites from 24 patients were sequenced by next-generation sequencing. Microbial DNA was extracted and 16S rRNA gene was amplified.

Tooth loss and radiographic bone loss in patients without regular supportive care: A retrospective study.

Background: Very few studies have investigated the effect of patient and site factors on periodontal progression and long-term tooth loss in populations with minimal dental care. The aim of this retrospective study was to assess tooth loss and radiographic bone loss over at least 5 years in patients attending a national-health service primary care practice in Sicily and undergoing no regular care.

Methods: Records of two hundred consecutive patients with at least 5 years follow-up were screened and demographic, clinical and radiographic data were retrieved.

Periodontal furcation lesions: A survey of diagnosis and management by general dental practitioners.

Aim: The aim of this study was to explore general dental practitioners' (GDPs) attitude to periodontal furcation involvement (FI).

Materials And Methods: An online survey focused on diagnosis and management of periodontal FI was circulated to GDPs in seven different countries.

Results: A total of 400 responses were collected.

Minimally Invasive Surgical Strategies in Regenerative/Reconstructive Periodontal Therapy.

Focused Clinical Question: After a quick overview on the original principles of guided periodontal regeneration (GTR), the aim of this paper focuses on the advantages of minimally invasive surgical techniques for periodontal regeneration/reconstruction. The specific clinical question to answer is: Are there new clinical parameters useful to choose the best minimal invasive surgery approach for each periodontal defect? An update of the decision trees is to propose after highlighting some clinical parameters deemed relevant for the choice of the most suitable minimally invasive surgical approach and which therefore are considered by us having a place in the new decision trees.

Summary: Starting from the paper of Evian dated 1985 until that of Aslan in 2017, we have analyzed the minimal periodontal surgical techniques proposed for the periodontal regeneration.
